(E)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-2-{4-[(4-chlorophenyl)methoxy]-3-methoxyphenyl}ethene-1-sulfonamide (CAS 478080-68-1), molecular formula C24H22Cl2F3N3O4S and molecular weight 576.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-2-{4-[(4-chlorophenyl)methoxy]-3-methoxyphenyl}ethene-1-sulfonamide (C24H22Cl2F3N3O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
